ABSTRACT

Introduction: The regulation of the sports walk specialty is strict, and one of the most controversial, being directed to technical gesture evolution of athlete and his execution speed, causing difficulty to perceive if the athlete lost contact with the ground or flexed knee.
Objective: To analyze the biomechanical differences between beginners and high-performance sports athletes, knowing the performance impact.
Methods: We studied two independent samples that exercise in the training track "Los Chasquis", Quito, Ecuador (High Performance: 1 subject, Beginners: 4 subjects), comparing the degrees values with the Mann-Whitney U test (p≤ 0.05), data obtained from various video analysis through the Kinovea software.
Results: All the analyzed variables of simple support phase (Traction and Mainstay), the double support phase (Impulse and Double support phase), step length in cm, the execution time (s), and the severity center of X-axis and Y-axis did not show significant differences when comparing the high performance athlete angles and initiation athletes, although there were differences in the average ranges with a lower movement angle for the high performance athlete.
Conclusion: No significant differences were found between the two independent samples studied, although there were different average ranges that should be analyzed comprehensively. It emphasizes the frequency importance and stride amplitude of athlete, in addition to impeccable technical execution of the sports walk phases.
